- Salutations,
-
- Not being a real techy I was pondering this question last night and wondering
- why I couldn't come up with an answer.
-
- An Arm2 runs at 8Mhz and has approx "mippage" of 4
- An Arm3 runs at 26Mhz and has approx "mippage" of 13
-
- Rumour has it that the next ArmX chip runs at 50Mhz and has approx mippage of
- 28
-
- Now then, what I don't understand is the Arm3 has a 4k cache which helps to
- speed things up, right?
- The Arm3 (most common ones) are approx 3 times faster than an Arm2 - is this
- because they are clocked 3 times faster?
-
- If so, where does the cache help?
-
- Taking this argument to the next ArmX at 50Mhz - it runs approx twice as fast
- as the Arm3 (again clock speed is "doubled") so shouldn't this be faster still
- due to improvements on the design off the chip?
-
-
- Someone, please explain this to me
-
-
- Confused
